Elby Designs Synthacon Filter Eurorack Module
This module is a "tribute" module, based on the awesome Steiner-Parker Synth VCF. Resonance is a bit unusual in its behavior. Once it starts oscillating, the resonance pot needs to be backed off a fair way to get it to stop again. It can also be frequency dependent. This module includes an input mixer. Each of the filter type inputs has its own level control. The all input is also affected by these level pots as it mixed with the individual inputs prior to the level controls. If using only a single input, it may be better to feed the signal into the all input, and adjust the level pots to select lp, bp or hp, rather than changing the patch cord between the specific input jacks.
This module has a maximum current draw of 15ma. It requires 14 hp/te worth of space to fit in a eurorack frame.
